SPECIFICATIGN forming part of Letters Patent No. 307,477, dated November 4, 1884.

Application filed June I], 18873. Renewed May 12, 1884.

LC?! (LZZ whom it may concern.-

Pe it known that I, J nssn LOOKHART, a of Niantic, county of Macon, and State of Illinois, have invented certain new and useful Improvements in Railways, of which the following is a specifica tion.

This invention is in part 8.Il-l[[11310V61]16]1l7 on the device shown in Patent No. 229,538, granted to me July 6, 1880; and the object to be obtained is an increase of stability and durability.

In the drawings accompanying'and forming a part of this specification, Figure-l is a side elevation of a pair of my rails placed in position, but not secured. Figs. 2 and 3 show the fornn of the bars used to complete the joint. Fig. 4 is a side elevation of a joint of my railway complete.

A represents an end of a rail provided with offseta.

B represents the end of the contiguous rail, provided with offset Z1 and extension I).

c is a bar provided with block (Z, that fits in the opening formed by offsets a b.

e is a bar provided with recess f, that fits over the end of block d.

(No model.)

I c and e are placed on the sides of the railjoints, and secured by bolts passing through holes 19 p.

g 5 are clamp-blocks loosely mounted on rod 0.

h h are nuts provided with diametrical grooves on their faces.

Rod 0 extends across the track, and is secured to the opposing rails by clamps g g.

When block (Z is placed in position in the rails and bars 0 and e bolted together, as indicated, an interlock is formed that makes the joint of great stability, and the holes 19 may be made sufficiently oblong to compensate for all expansion and contraction.

I claim The combination of rail A, provided with offset a, rail B, provided with offset 1) and ex tension Z2, bar 0, provided with block (I, and bar 6, provided with recess f, all secured in position, as and for the purpose set forth.
